r srncmcn'ron varming pm of Leaersratent No'. 762,422, datei Jun rgie l. f Application nea october o, i903.; sum in. 179,21 1. 1 1'i0`mtd`1 Be itlknownf'that I, JOSEPH E. LEMYRE, a citizen of the United States, residing in Manchester, inthe county of Hillsboroand State of New Hampshire, have invented a new and' useful Improvement in Bobbins for Cotton- Looms, of whichthe following is'a specication.

This invention relates particularly to bobbins of the style provided with a filling change, 'In bobbins of this style there is ordinarily left on the bobbin a large bunch of thread. This isfor the reason that in bobbins of this character the -feeler strikes the thread on lthe bobbin until it is suiriciently reduced to avoid the feeler and enable the bobbin to be thrown off. This throwing off occurs, however, when there is a considerable bunch of thread left at the point where the feeler strikes, such thread being, of course, wasted.

1t is the object of this invention to do away with this waste and utilize almost all of the thread or yarn,'so that when the bobbin is thrown off there is but very-little thread left wound around it, and I accomplish this result mainly by the employment of a cone on the spindle, said cone receiving the blows of the feeler and being held in position by the thread until but little thread is left on the spindle, when the cone falls or yields and allows the bobbin to be thrown off.

The nature of the invention is fully described in detail below and illustrated in the accompanying drawings, in which- Figure lisa longitudinal section 'of the bobbin in a full condition. Fig. 2 is an eleration ofthe bobbin with the thread nearly unwound from it and the cone in a position to allow the bobbin to be thrown oif. The

Alocation of the feeler is indicated in both tigspindle at a suitable distance from the head.

The portion (l of the spindle which liesbetw'een the ringel and the head l: is substan- -slope up toward the head Patented June 14,

Onth 1s p .e hollow., eenes y. preferably, .effmetahasaid cone beingr tapered on its inner surface, as well as its outer surface, as shown in Fig.. 1. The cone is formed up near its larger end with an annular rib 7L. and said end is of suitable size to overlap said shoulder e, as indicated by the portion k. The ring e confines the cone between it and the head of the spindle. When the spindle is' loaded, the thread ex- 1 and is wound around the cone g (whose portion overlaps the inner edge of the head) un til tends around it in the manner indicated in Fig.

the thread covers the main portion of the cone l up to the rib L. This rib is left bare and is so located that it will receive the blows of "the feeler.

dicated in Fig. 1; but whenthe thread is un- Wound therefrom the cone slips off from the head and falls loosely on the portion d of 'the' constructed 'the bunch of thread whichi rtamains after the feeler ceases to strike it isj As long as there is any v'thread lefton the cone it will remain in the position inquite large in my invention the thread is all tion 'left on the spindle by the time the cone is released bythe unwinding of the thread, so as to fall and leave a space into whichvthe feeler fiies without striking the cone. Hence when the picker throws oif the bobbin with my construction there is but little thread left .unwound from the cone and onlya small 'pore wound around it. while by the ordinary'con- 1. In a bobbin of the character described, a

cone on and around the spindle near the head 'and in the path of the feeler, said cone beingi into the path of the feeler,V for the purpose ,2O

adapten to beheld rigidly by the thread until said thread is nearly orl quite un'wound therefrom and then to fall away from the'pkath'of '.5 said feeler, for the purpose set forth.

" 2. In a bobbin of the'character described, the spindle provided with a suitable head; and the cone g normally loose on said spindleand provided with the annular rib t adapted when 1o the yarn is woundaroundjthe main porti-0n of the cone to extend into Athe path of the feelexyfor the purposes'et forth..

3. In abobbin of :the character described,

the spindle provided with a suitable head; and ,IS' fthe cone g' normally loose on said spindle, provided with the annular,` rib and outer end 7c, whereby when the yarn is wound around the main portion of the cone said outer end overlaps and rests on the head and said rib extends set forth. i s y 4. In a bobbin ot the character described, the spindle provided with a suitable head; a 'ring rigid on the spindlev at a short distance from the head; and a cone on and around the 25 spindle between the ring and'the head and in the path of the feeler, said cone being adapted to be held rigidly by the thread until said thread is nearly or quite unwound therefrom and then to fall away from the path of the 30 feeler, for the purpose set forth.

In testimony whereof I have signed myname to this specification in the presence of two subscribing witnesses.
